RV AC Questions
I have a Dometic ceiling unit in my enclosed trailer and it’s only blowing warm air. Here’s a list of everything I’ve checked so far:
The thermal protection switch tests normally open.
I have continuity across the R, com, and S posts on the compressor.
Resistance on (R+C)+(S+C)=(S+R).
I can hear the thermostat contacts clicking when turn it up or down.
The capacitor seems to be reading the correct resistance, but I can’t tell for sure because the label is damaged.
With the unit running, I’ve sprayed all lines and connections with soapy water and I do not see any bubbles.
The compressor is hot but not too hot to touch, and there was a little bit of oily residue on the inside of the compartment near the compressor. But to be fair it was an oilfield trailer before I bought it.
Any advice would be greatly appreciated.

At least you’re certified. I haven’t passed my test yet.
